Abstract
In order to provide the Russian paint and varnish industry with cheap domestic raw materials, research has been carried out to develop a phosphor pigment that meets the following requirements: 1) the production cost per unit of its volume should not exceed the cost of a similar volume of traditional dyes; 2) the pigment should be made exclusively from domestic raw materials. Sulfides were chosen as the most optimal raw materials, because of a fairly simple technology and the possibility of using production waste as a raw material, namely phosphogypsum. The essence and theory of the method for obtaining a phosphor pigment from phosphogypsum, as well as the technological features of its production.
